For people who are overweight, need to lose weight or have too much body fat, running on an empty stomach in the morning helps to consume a lot of fat and is effective for losing weight.

I think if the running time is less than 30 minutes, it is enough to supplement some sports drinks, while friends who run for more than 30 minutes need to simply eat something in the morning, which can be eaten very little, but running on an empty stomach for so long is too harmful to their health.
For example, many people say that people who lose weight run well in the morning because there is not much glycogen in their bodies after a night of consumption. Therefore, morning running can enter the fat burning state as soon as possible, and the weight loss effect is better. However, if you are full and run, the things in your stomach have not been digested before, and your heart is so heavy.

For morning running, from the point of view of health and comfort, it is suggested that you can eat properly about 90 minutes before running, so that the food can be properly digested, which can not only provide enough energy for subsequent running, but also avoid feeling hungry during subsequent running. Running on an empty stomach in the morning is good for dieters. Running consumes our glycogen. Running will consume glycogen accumulated last night when there is no energy supplement in the morning. Running on an empty stomach will increase our fat burning rate.
